An implementation of the algorithm outlined here for submitting form data as JSON. Convert any form into a structured JSON object.

Submitting this form

<form enctype='application/json'>
  <input name='places[0][city]' value='New York City'>
  <input type='number' name='places[0][population]' value='8175133'>
  <input name='places[1][city]' value='Los Angeles'>
  <input type='number' name='places[1][population]' value='3792621'>
  <input name='places[2][city]' value='Chicago'>
  <input type='number' name='places[2][population]' value='2695598'>
</form>

uploads this object

{
  "places": [
    {
      "city": "New York City",
      "population": 8175133
    },
    {
      "city": "Los Angeles",
      "population": 3792621
    },
    {
      "city": "Chicago",
      "population": 2695598
    }
  ]
}

Include the script in your page and any form with an attribute of enctype set to 'application/json' will submit data with a json payload.
